EV1531DQ-002A 2.7-5.5V Triple Output Step-Up Plus Charge Pump Evaluation Board SOT-23

The MPS EV1531DQ-002A is an evaluation board built around the MP1531 for bench characterisation of the device in its intended topology. It operates from a 2.7 V to 5.5 V input and switches at 250 KHz. The board carries the device in its SOT-23 package.

The EV1531DQ-002A Evaluation Board is designed to demonstrate the capabilities of MPS' MP1531 triple output step-up converter with charge-pumps.

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
